T0 ALL WHOM lI 'l MAY CONCERNg: 4 Bo it known that I, JAMES BRAGDON, ofBoston, in the county of Suffolk, and State of Massachusetts, have invented an Improved Glue-Pot; andi 1'v do hereby'deelare that the followingftakenl in connection with the drawings which accompany and form part of this specification, is a description 'bf my invention suieient to enable those skilled in the art to'px'actiseit.

. My invention relates to'the construction of a vglue-pot,-vvith reference to heatingithe Water-containing vesselv into which the glue-pan4 is set, n'ith the flame of a kerosene-lamp.

Under the present construction of glue-pots, and lamps for the same, it isiimpracticable to use kerosene an'df:

similar oils for the heating-fuel, both en account of the-smoke from theA blaze; as there can'beno chimney to `the lamp; as in an'ordnary kerosene-lamp,) and because the cap of thelamp becomes'so heated fromco'niine# ment of the blaze,and other volatile products of combustion, as to draw up the oil, and cause it to overflow and'- Vivnlnme upon the to'p andsides of the lamp.

My inventionlis intendedl to obviate these defects, and consists in combining with the stove a conical'hcatimpinging plate, forming the bottom of'the Water-containing chamber, with an inclined smoke-line leading from the point of the cone tothe side of' the'llue, where it opens into a vertical flue leading to the top ofthe stove,

`and in combining with the stove and such.heat-jmpingingplate and fines a lamp, having a central tube or ycham- .ber leading from the capte theV bottom ofv the; lamp, with space enough beneath the tube to allow the oil to be drawn from the oil-reservoir up into'theftube by capillary attraction, the tube being packed tightmith fibrous llns l The drawing represents a section of my improved gluepot. `a denotes the stove or casing, Y) the lamp, c

the water-containing vessel,` d the glue-pan. The stove is made with one'or, more openings, e, which may be closed wholly or partially by a ring,f, which slides rotatvely on the casing a, thisripg having anopening or openings corresponding to the opening e.' In the lower part of the stove is 'the oil-lamp b. .In the centreof. the oil-containing reservoir is a tube, g, which is fixed to and extends ldown from the'cap-ring h, this; tube'being closed from the ring to its lower end,so as to have no communication hatevcr with such tuba-excepting at said bottom, which is left open, but'eXteDds nearly don'n to thebottom of the reservoir, as seen in' the drawing;

This tube is stuffed with vfibrous material, packedl tightly within it, and as there is`no-airinlet into the oilreservoir excepting through this' packing andthe wick-tube, the oil only rises into the filling and to the wick by capillary attraetion,.by which means the lamp is'prevented from overioyvingi- The water-containing vessel c, inthe upper part of the stove,"has a conical bottom, z', the point ofthe cone extending doivn towardsthelamp, as seen in the drawing. The water in this vessel does not extend up to the i glue-pan, but only to the top or part way to the top ofthe conc-shaped bottom thereof,- leaving a steam-chamber all around the bottom and sides of the glue-pan, so that the steam generated by the boiling vater heats the glue-pan anddissolves the glue, the water of condensation flowing down-the sides of the steam-chamber back to the water-chamber. YA safety-outlct, c, may be provided for escape of the excess of steam.

Ox; one side of the inclined bottom a Hue, Z, is made, this flue opening at its lower-'end over ornearly over the centre of the lamp, and at its upper' end into a vertical flue, m, open at top and bottom, as seen in the drawing. As the smokei and other volatile products of combustion ascend from the blaze, they aredrawn into the heel, the current ofA nir ascending through flue m creating a draught, which accelerates draught through luel.

While the smoke is thus all drawn into the luekand 'escapesat the top of the stove, the heat, striking the point of the cone, is disseminated from this point over all sides of the heat-impieging bottom, z'.

. It will thus be seen thata kerosene-lamp may be used for heating glue-pots -without any of the dangers or troubles attending the use of lamps as commonly constructed in glue-potsas commonlyl constructed, the construction and arrangement of parts being simple, and making a rcry neat, reliable, and effective glue-pot.

I claim, in combination u'ith'the glue-pau or vessel d, the watercontaining vessel c, made with theconical bottoui'z', :ind the steamfchamber j, andxhaiving beneath it the inclined flue l, f or escape 'of the smoke.fiom tbc 1a.mpall substantially as shown :tud described. f v

' I also claim, in combination with the conica l bottom unil-.flue lithe vertice-l flue m, substantially as shown and described.

' Il, also claim, in combination with the conic al bottom and flue the lar-np having n. packed tube, g, subf i stantially as'described.
